+## Overview
+
+All Mostro messages are [Parameterized Replaceable Events](https://github.com/nostr-protocol/nips/blob/master/01.md#kinds) and use `30078` as event `kind`, a list of standard event kinds can be found [here](https://github.com/nostr-protocol/nips#event-kinds)

+## Paying a hold invoice
+
+When the seller is the maker and the order was taken by a buyer, Mostro will send to the seller a message asking to pay the hold invoice, the message will look like this:
+
+```json
+{
+  "version": "0",
+  "order_id": "ede61c96-4c13-4519-bf3a-dcf7f1e9d842",

+        "fiat_amount": 100,
+        "payment_method": "face to face",
+        "premium": 1,
+        "created_at": 1698937797
+      },

+    ]
+  }
+}
+```
+
+After the hold invoice is paid Mostro will send a new message to seller with the following content:
+
+```json
+{
+  "version": "0",
+  "order_id": "ede61c96-4c13-4519-bf3a-dcf7f1e9d842",
+  "pubkey": null,
+  "action": "BuyerTookOrder",
+  "content": {
+    "SmallOrder": {
+      "id": "ede61c96-4c13-4519-bf3a-dcf7f1e9d842",
+      "amount": 7851,
+      "fiat_code": "VES",
+      "fiat_amount": 100,
+      "payment_method": "face to face",
+      "premium": 1,
+      "buyer_pubkey": "npub1qqqt938cer4dvlslg04zwwf66ts8r3txp6mv79cx2498pyuqx8uq0c7qkj",
+      "seller_pubkey": "npub1qqqxssz4k6swex94zdg5s4pqx3uqlhwsc2vdzvhjvzk33pcypkhqe9aeq2"
+    }
+  }
+}
+```
+
+Mostro also send a message to the buyer, this way they can both to to each other in private, this message would look like this:
+
+```json
+{
+  "version": "0",
+  "order_id": "ede61c96-4c13-4519-bf3a-dcf7f1e9d842",
+  "pubkey": null,

+      "amount": 7851,
+      "fiat_code": "VES",
+      "fiat_amount": 100,
+      "payment_method": "face to face",
+      "premium": 1,
+      "buyer_pubkey": "npub1qqqt938cer4dvlslg04zwwf66ts8r3txp6mv79cx2498pyuqx8uq0c7qkj",

+    }
+  }
+}
+```
+
+## Ephemeral keys
+
+Mostro clients should use ephemeral keys to communicate with Mostro, indicating the pubkey where they want to be contacted in the `pubkey` field of the message, this way orders and users can't be easily linked, `buyer_pubkey` and `seller_pubkey` fields are the real pubkeys of the users.
